Subject: Re: slaving z-80 to an 8086..

Macrotech International (the firma that sells a 1Meg S-100 memory board)
will be introducing a CPU board designed to be a plug-compatible
replacement for the Compupro 8085/88. It will sport a Z80B at 6MHz
and an 80286, also at 6MHz I believe. They had not planned to implement
the circuitry necessary to allow the use of 8 bit wide memory, but
discovered that MPM-816 has some quirks that makje this a necessity. It
is therefore back to the drawing board. My latest report is that
the mark two design is complete and pc board artwork will commence
momentarily. Macrotech expects to have a wirewrap prototype at Comdex;
I will have one of the first real production run of pc boards and will
reort at that time (time frame is 1-2 months from now). This board
should really be a spped demon, but it will not be cheap. Macrotech
seems to be committed to leading edge technology for high-powered
multiuser systems, such as G&G systems, Alpha Micro (a major
customer for their ram boards), etc., and price is secondary to
performance.
